Hole-burning effect based on light multiple scattering in Sm2+ -doped glass powders

Abstract

Room-temperature persistent holes are burned in frequency and wave-vector domains for multiple-scattering optical media based on Sm²⁺-doped glass powders. This phenomenon stems from three-dimensional random interference speckle patterns in disordered media. In our previous studies, we reported that the width of holes depends on the transport mean free path, the absorption length, and the sample thickness. In the present investigation, the effect of the polarization of incident light on the hole formation is demonstrated.
